J I am so sorry your arms are not in good shape, not just for the PC but for so many things; I just went through that with my shoulder joints and it amazes me just how many things we take for granted when we do them, using our arms!
Get well wishes your way and keep lurking; I think the group would fall apart without our lurkers and watchers; I know I can feel you all out there <g> over my shoulder!
Keep on keeping on!
